We felt that way through minicamp, into fall camp and in the preseason. That was one of our expectations, that we were able to execute and we were going to be efficient on offense."Locker picked apart a Kansas City defense that lost linebacker and starting defensive tackle to Achilles injuries. He finished 22 of 33 while connecting with eight different players, including former wide receiver ."Jake did great," Whisenhunt said.

Succop followed with a field goal later in the half for a 10-0 lead.Johnson went down with his Achilles injury just before the half, and DeVito was lost to a nearly identical injury on the first drive of the second half.Locker capped that drive with a short TD pa s to Wright, who managed to contort his body just enough to touch the pylon as he was going out of bounds. The touchdown gave Tenne see a 17-3 lead and started a shower of boos from a crowd that had been full of optimism."Those are guys who are kind of staples of their defense," Locker said. "They were in there almost every snap, especially Derrick. You understand that's going to change up their personnel a little bit. Yeah, you look at it and maybe understand where you can gain an advantage."It was an important opener for the injury-prone Locker. The declined their fifth-year option on him in in the offseason, so the pre sure is on Locker to perform this season.He certainly did against a defense that was full of questions entering the season, and has even more after a pair of serious injuries to key defensive players."I have a lot of respect for Coach Reid and this football team and these fans," Whisenhunt said.
